Setup Instructions
Step 1
Connect the battery positive and negative terminals as indicated (+POWER-) on the controller.
Step 2
Connect the pump motor to the positive and negative terminals as indicated (-MOTOR+) on the controller.
Step 3 (Optional)
If using a Temperature Probe, it may be connected at any time. If a probe is connected temperature control will
be active. If no probe is connected, temperature control is not used.
Step 4
Flip the toggle from the OFF position to the RUN position to begin pumping.
Step 5
OPTIONAL MODE SELECTION – Once you have flipped the toggle to the RUN position, you may hold the
rotary knob down until the screen alternates between modes. The available mode options are as follows:
Cycles per Minute Mode: Cycles = 1-10, Duration = 0.5 to 5.5
On Time Mode: 0.5 seconds to 5.5 seconds-half second increments
Temperature Mode: 30*F-90*F
Remote Input Mode: 4-20mA
Modbus Mode: RS-485
NOTE: The default settings are in Cycles per Minute which are half seconds.
*Battery voltage must be above 10 volts for operation. The battery display will show when the battery is too low for pump operation.

Operation
Step 6 (Setting the Controller for - CpM, ON Time, OFF Time, or Temperature)
When the Power Switch is flipped to RUN, a quick self-test is performed and then the battery voltage display
will be selected and displayed on the seven segment display.
Pressing down on the Rotary knob will select/cycle through different displays as indicated by the LEDs. The
display parameters are Cycles per Minute, Duration (On Time), Temperature ON set point, Temperature OFF
set point and Battery Voltage / Temperature probe reading.
To set an operating parameter (Such as Cycles or Duration), Press the rotary Knob Down Quickly (it will click)
to cycle to the parameter you want. Each press takes you to a different parameter that is displayed. When you
have selected the parameter you want to change as indicated by the LEDs on the left column of the controller,
you rotate the knob clockwise or counter clockwise to change this parameter setting up or down. When you
have selected the new value you want Press and Hold the knob down for approximately three seconds, you will
see SAV displayed indicating the new parameter set point has been saved. If you do not press and hold until SAV
is indicated the setting is not saved. If you continue to hold down the knob for two more seconds after SAV
display a pump prime cycle will occur (and the parameter will NOT be saved). The display will indicate a prime
cycle by displaying PRI and then start a 30 second count down.
The above is used to change each setting as desired. If the controller is in Modbus or Remote Input mode, this method will be disabled locally.
Step 7 (Priming)
To enter the Prime mode, Hold the rotary knob down for 5 seconds. During Prime the Pump will remain on for
30 seconds until timed out, at this point normal operation will begin. Press the knob again during a prime cycle
to extend the prime cycle time another 30 seconds if needed. To Abort the Prime Cycle, you must turn Off the
Power Switch.
Modbus/RS-485 & Remote Input/4-20mA
Step 8 (Optional Modbus, Remote Input)
A Plug in Terminal Block is used for connection to on-board Modbus and the Remote Inhibit input. The
Modbus register map is a subset of the current TXAM Modbus register map. A dry contact connected to the
Input will inhibit pump operation when closed and this is indicated by INH being displayed when pump
operation is inhibited. The Connections are designated on the controller to the left of the 5-pin connector. The
first three pins can be utilized for Modbus mode (D-, GND, D+) and the third pin down can be utilized for
Remote Input mode (D+, INPUT, GND).
